Schizophrenia is a chronic mental health condition affecting 1% of human populations, with symptoms that include visual and auditory hallucinations, delusions and disordered thought, leading to disruption of the sense of self.

Abstract. Paranoid delusions are the most common symptom of psychosis but less severe forms of paranoid ideation and mistrust are common in everyday life and lie on a continuum with the rarer clinical forms (Elahi, Perez Algorta, Varese, McIntyre, & Bentall, 2017).
